HomeFlySpeed SQL Queryhi


I want to add two count results in a single query.

e.g I get two count results as below ..

select count(*) as count1 from Books where condition1

select count(*) as count2 from Books where condition2

Now I want add these two counts and get the total count.

Can I all these stuff in a single query ?

How do I do this in FlySpeed SQL ? I need help at this part...

Dear Pagoda,

(select count(*) as count1 from Books where condition1) +
(select count(*) as count2 from Books where condition2) as total

Yes, it is possible. Go to an empty Expression cell of the Query Columns grid below the Design area. Right click on it and select the "Insert sub-query" menu item; type "+", right click again and select the "Insert sub-query" menu item one more time. After that go to the Alias cell and type "total". You will see two sub-query tabs above the Design area. Go to each sub-query tab, add the Books table, click the asterisk item in the Field list, go to the Aggregate column of the Query Columns list and select "Count", add the necessary conditions.
